i have a 93 ex that i put a 00b16a2 in. Does this meen i will need to wire for knock sensor.. When i did the swap, i had a left over plug on the right side of the engine bay near where the resister box would sit on older civics. We just plugged that right into my knock sensor.. but , according to my other posts for my speedometer not working all the time and losing power during exceleration this could be my problem? ?

A D16Y8 does have a knock sensor !!!! I believe any motor with vtec had a knock sensor. I could be wrong on the vtec issue, but I went through 3 knock sensors and some timing adjustments before I could pass emissions on my 99 Civic EX (D16Y8)...
